=head1 NAME
db-ris - Interface to the DeutscheBahn online departure monitor
=head1 SYNOPSIS
B<db-ris> [B<-d> I<date>] [B<-m> I<motlist>] [B<-t> I<time>] [B<-v> I<via>]
I<station>
=head1 VERSION
version 0.0
=head1 DESCRIPTION
db-ris is an interface to the DeutscheBahn departure monitor
available at L<http://reiseauskunft.bahn.de/bin/bhftafel.exe/dn>.
It requests all departures at I<station> (optionally filtered by date, time,
route and means of transport) and lists them on stdout, similar to the big
departure screens installed at most main stations.
=head1 OPTIONS
=over
=item B<-d>, B<--date> I<dd>.I<mm>.I<yyyy>
Date to list departures for. Default: today
=item B<-m>, B<--mot> I<motlist>
Comma-separated list of modes of transport to show/hide. Accepts the following
argements:
ice InterCity Express trains
ic_ec InterCity / EuroCity trains
d InterRegio and similar
nv "Nahverkehr", RegionalExpress and such
s S-Bahn
bus
ferry
u U-Bahn
tram
You can prefix an argument with "!" to hide it. The default is C<<
ice,ic_ec,d,nv,s >>. Note that B<-m> does not replace the default, so if you
only want to see S-Bahn und U-Bahn departures, you'd have to use C<< -m
!ice,!ic_ec,!d,!nv,u >>.
=item B<-t>, B<--time> I<hh>:I<mm>
Time to list departures for. Default: now.
=item B<-v>, B<--via> I<regex>
Only display trains whose route (all stations between the current stop and the
destination) matches the perl regular expression I<regex>. The match is not
case-sensitive. Use '^regex$' to match a full string, but be aware that this
may not work as expected.
=item B<-V>, B<--version>
Show version information
=back
=head1 EXIT STATUS
Zero unless things went wrong.
=head1 CONFIGURATION
None.
=head1 DEPENDENCIES
=over
=item * Class::Accessor(3pm)
=item * LWP::UserAgent(3pm)
=item * XML::LibXML(3pm)
=back
=head1 BUGS AND LIMITATIONS
There are a few character encoding problems (most notably, B<--via> does not
understand UTF-8 umlauts).
